Member Function Documentation

static vtkUnstructuredGridVolumeRayCastMapper* vtkUnstructuredGridVolumeRayCastMapper::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkAlgorithm.

static int vtkUnstructuredGridVolumeRayCastMapper::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkUnstructuredGridVolumeMapper.

virtual int vtkUnstructuredGridVolumeRayCastMapper::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkUnstructuredGridVolumeMapper.

static vtkUnstructuredGridVolumeRayCastMapper* vtkUnstructuredGridVolumeRayCastMapper::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkUnstructuredGridVolumeMapper.

virtual vtkObjectBase* vtkUnstructuredGridVolumeRayCastMapper::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkUnstructuredGridVolumeMapper.

vtkUnstructuredGridVolumeRayCastMapper* vtkUnstructuredGridVolumeRayCastMapper::NewInstance ( ) const

Reimplemented from vtkUnstructuredGridVolumeMapper.

void vtkUnstructuredGridVolumeRayCastMapper::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkUnstructuredGridVolumeMapper.

virtual void vtkUnstructuredGridVolumeRayCastMapper::SetImageSampleDistance ( float ) [virtual]

Sampling distance in the XY image dimensions. Default value of 1 meaning 1 ray cast per pixel. If set to 0.5, 4 rays will be cast per pixel. If set to 2.0, 1 ray will be cast for every 4 (2 by 2) pixels.

virtual float vtkUnstructuredGridVolumeRayCastMapper::GetImageSampleDistance ( ) [virtual]

Sampling distance in the XY image dimensions. Default value of 1 meaning 1 ray cast per pixel. If set to 0.5, 4 rays will be cast per pixel. If set to 2.0, 1 ray will be cast for every 4 (2 by 2) pixels.

virtual void vtkUnstructuredGridVolumeRayCastMapper::SetMinimumImageSampleDistance ( float ) [virtual]

This is the minimum image sample distance allow when the image sample distance is being automatically adjusted

virtual float vtkUnstructuredGridVolumeRayCastMapper::GetMinimumImageSampleDistance ( ) [virtual]

This is the minimum image sample distance allow when the image sample distance is being automatically adjusted

virtual void vtkUnstructuredGridVolumeRayCastMapper::SetMaximumImageSampleDistance ( float ) [virtual]

This is the maximum image sample distance allow when the image sample distance is being automatically adjusted

virtual float vtkUnstructuredGridVolumeRayCastMapper::GetMaximumImageSampleDistance ( ) [virtual]

This is the maximum image sample distance allow when the image sample distance is being automatically adjusted

virtual void vtkUnstructuredGridVolumeRayCastMapper::SetAutoAdjustSampleDistances ( int ) [virtual]

If AutoAdjustSampleDistances is on, the the ImageSampleDistance will be varied to achieve the allocated render time of this prop (controlled by the desired update rate and any culling in use).
